Population Dynamics Of Yellow Stem Borer Scirphophaga Incertulas (Walker) On Rice (Oryza Sativa): Using Sex Pheromone Trap At Shivamogga District, Karnataka.
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 10
Abstract
The insect Scirpophga incertulas commonly known as yellow stem borer (YSB) of rice is distributed widely, covering almost all Asian countries, YSB usually occupied more than 90% of the borer population in the rice crop from seedling to maturity stage of the crop their infestation caused “Dead heart” at vegetative stage and “White ear” at reproductive stage respectively. Pheromone traps are the convenient tool to monitor adult male moth population of YSB in rice field. The present investigation was under taken at purle village, Shivamogga, Karnataka to monitor the population dynamics of YSB using sex pheromone trap during summer and kharif seasons 2017. The experimental result revealed that the YSB moth catches reaches its peak during 17th standard week (44.4 moths/week) during summer and 38th standard week (36.2moths /week) during kharif respectively.
